On a road course with a decent suspension and properly driven the 1 series will be fastest with the stock rear bar or no bar at all, period. 3 series will behave the same way. The only time I can see the car being faster with a larger rear bar is when really soft spring rates, LSD, wider wheel and tires or the combination of the three.
